“6” + 5 =

I understand if "5"+"5" is 25 or "6"+"6" is 36, but what if both numbers aren't in quotations? What does this equal?

is a case of "type coercion".

Just to be clear: "" :point_left: these are quotes (not parentheses).

So when you combine a string with a number, the compiler does something called type coercion where it tries to make the arguments the same type. In this case, it converts the number into a string, and then it handles it the same way it would if you started with this: "6" + "5".

When you put double quotation marks around a character, you asking that the character 6 be used, instead of the value of 6. So if you run the code, as you displayed it, you should receive the character 6 concatenated to the character 5. That is, of course, if you use the var or string data type. If you use any other data type, you should receive an error.
